hi,
Check under "examples" for "Richard_Examples", there's a tree example
marked
"Richard_fast_tree_example_500.htm" , which uses only about 24 layers to
display 500+ nodes,
as opposed to 1000+ layers. It's not quite finished yet, and I hope to
include some doc's still,
but you can use the example to test if ram usage will be ok, and download it
if necessary from the
"download" section.
Cheers,
Richard :o

(ie tested only 'cause ns won't run anymore at the moment)
(All are ported to the latest snapshot of DynAPI2.)
